Hydroponic plants require a number of elements to grow in a healthy way that include nitrogen (N), Phosphorus (P) and Potassium (K) along with some trace elements such as sulfur, iron, manganese, zinc, copper, boron, magnesium, calcium, chlorine, and molybdenum. Nitrogen (N) is an essential element, important for leaf and stem growth, phosphorus (P) is for root growth and potassium (K) is needed for healthy plant growth. Hydroponic nutrients are divided into macro nutrients and micro nutrients. Nutrients needed in very small amounts are micronutrients and those are needed in larger quantities are called macronutrients. The nutrients in a hydroponic system are mixed with the water and sent directly to the root system. Below is a framework which you should consider to feed your plants with hydroponic nutrients:

Whatever the size of your hydroponic garden, you need to feed your plants with ½ to 1 gallon of hydroponic nutrient solution available for each plant in the system. Staying within this range will prevent your plants from changing the pH level frequently.

Try to feed your plants with three-part base nutrients that comprise grow, bloom, and micro nutrients. During the growth stage, you need to use grow nutrients. Grow nutrients contain the proper blend of NPK and other trace elements. Similarly, the bloom nutrient should also be mixed with micro nutrients during the budding phases of your plants.

If you want the biggest, most colorful, aromatic, and most impressive hydroponic garden then you should use the finest quality of three-part nutrient products. As a hydroponic grower you would like the simplicity and easy-mixing feature of these hydroponic products.

Plants need different nutrients throughout the various stages of its life. The amount of each fertilizer to use and at what time in the growing cycle is determined by a feeding schedule, for example, seedlings require different ratios of nutrients than a plant in its bloom stage.

In addition to regular food, there are a few additives such as vitamins, trace nutrient supplements, and plant hormones that help to create healthy and productive plants. You can also use silica as additive to boost the immune system of your plants.

If you are using a seaweed based fertilizer, remember to add some additional liquid seaweed.

The required pH range of hydroponic solution usually varies from plant to plant, however the vast majority of plants fall in the range of 5.0 to 7.0. Get a pH test kit to test the pH level of your hydroponic nutrient solutions.

To grow organic plants with the help of hydroponics system, you need to feed your plants with organic hydroponic nutrients. The choice and use of hydro-organic nutrients will depend on the crop you are growing and its stage of growth. Since plants have different nutritional requirements in seedling and vegetative stages, the mix of nutrients may differ from stage to stage. Some of the important organic hydroponic nutrients that you can use to feed your plants are homemade nutrients, fish waste, readymade hydro-organic nutrients and seaweed or kelp. By using organic hydroponic nutrients and hydroponic products, you can expect more colorful petals, rapid growth, bigger yields, and healthier plants.
